Welcome to the Samsung Galaxy Watch 4 update hub. Here you’ll find the latest information on software releases for Samsung’s latest smartwatches. We’ll detail the current firmware versions for the Galaxy Watch 4 and the Galaxy Watch 4 Classic and alert you if there’s a new update rolling out.
The Galaxy Watch 4 and Watch 4 Classic launched with Wear OS 3 and Samsung’s One UI Watch skin on top. During the Wear OS 3 unveiling, Google said it would issue more frequent updates to the platform, but the company has since told Android Authority it has “nothing to share” on how frequently it plans to issue new releases. Samsung will likely work with Google to issue major software versions for the Galaxy Watch 4 series while keeping its core One UI Watch apps updated constantly.
- Current stable version: Wear OS 3
Latest Samsung Galaxy Watch 4 series update
October 12, 2021: Samsung is rolling out another update to the Galaxy Watch 4 and the Galaxy Watch 4 Classic (h/t 9to5Google). If you were hoping for more feature additions, you’d be bitterly disappointed. The latest firmware, numbered R8**XXU1CUJ2, brings a brief, vague changelog hinting at “improved system stability and reliability.”
It’s unclear which issues the latest update fixes, but it’s essential to keep your firmware current. Head on over to Settings > Software update on your watch to check for new updates. Or open your Galaxy Wearable app on your phone, head to Watch settings > Watch software update.

Calorie measurements during cycling exercises and general stability improvements rounded up the patch.
- August 22, 2021: The first Samsung Galaxy Watch 4 series update rolled out even before the wearables started shipping. It carried firmware version R8**XXU1BUH5 and had a size of 290MB.
